OP's profile says he joined in '05 and has made 22 posts. Probably has been trying to deal with the problem or maybe jumped off a bridge...
If it's as bad as it sounds, I believe the worst problem will be mold growth, and some varieties like Stachybotrys (black mold) are extremely toxic. Mold loves food in the form of cellulose and there's plenty of that in the subfloor, cabinets, flooring material, luan wall paneling, etc. Water will have wicked up the walls and cabinetry from floor level. If the OP has been wintering in his RV over the winter, the interior humidity level is probably already higher than ideal, adding to the problem. Trying to dry the interior out by cranking the furnace up will raise the humidity level further and probably make it worse.
Mold needs water + food and just a few days to take hold and spread. You can't just spray some type of biocide like bleach for ex. all over and dry everything out and assume all is okay. Even dead mold is a problem due to the chemicals and proteins it creates and the reactions in humans. Porous materials like say luan make it even harder to deal with mold. Mold will be hidden in all sorts of places you won't see or find.
Worst case of property damage to a single family home I've heard of was a 12,000 sq. ft. mansion in Austin TX built as a replica of Glen Tara. A minor on-going leak caused widespread mold growth. The husband ended up with significant brain damage. Farmers Insurance offered them peanuts but the wife dug her heels in and battled them out in court and eventually got $32 million. The home was declared unlivable and had to be abandoned. This goes back about 20 years - story
